What HTTP methods do you know?

Main HTTP methods:

• GET — retrieve data from the server.
• POST — create a new resource or send data to the server.
• PUT — complete update of an existing resource.
• PATCH — partial update of a resource.
• DELETE — delete a resource.
• HEAD — get only response headers without the body.
• OPTIONS — request supported methods for a resource from the server.

Each method has its purpose and semantics, which is important to consider when designing REST APIs.
